The invention has f0.1 its primary object.

' to conserve moisture in the planting of seeds, thereby insuringgerminating in arid sections and during a drought. j

The inventionprovides a planter which prepares a bed' for the seeds, thelatter being covered with as little disturbance as possible, both to theseeds and the bed, thereby preventing rapid dissipation of the moislture.

and the merits thereof, reference is to be had to ythe followingldescription and Athe drawings hereto attached, 1n wh1ch,-

Figure 1 is a side View of a planter em-l bodylng the invention, thenear wing being omitted, and a portion of the standard being broken awayand the bed forming pointI being in section.

Figure 2`is a topplan view of the planter. Fi re 3ds an enlargedsectional view on the line 3-3 of Figure 1, looking in the di rection ofthe arrows,

' Figure 4 is a fragmentary elevationjal view showing more clearlyV thepivotal conf K3 5, nection between the front 'end of the coverers andthe wings of the runner and,

Figure'is a fragmentary view of the forward portion of the runnerinverted, or as seen from the bottom side.

Corresponding ,and like parts are referred to in the followingdescriptionv and indi-- cated in the several views "of the drawings bylike reference characters.

The planter consists of a runner embodyinganopener 1 and wings 2, saidparts being preferably formed of a sheet metal blank doubled uponitself, the fold corresponding to the opener 1 which inclines upwardlyand rearwardly and the folded porbotions constituting the wings 2 whichare rearwardly. The lower edges of the wlngs 2 are in akv higher planethan the lower edges of the. opener 1, as indicated most clearly inFigure 1, andthis is of advantageas lt'prei M vents the earthfalling'upon and disturbing the vbed 'ofl the furrow and the seeddeposf.

ited thereon. A filler 3v occupies the space formed between 'the lowerside portionvof the opener` 1 and this filler consists of a block havingits lower side in the same plane as the lower edges of the sideportions. of the' opener 1. The ller 3 reinforces the lower portion ofthe opener 1 and forms the bed of the furrow provided to receive theseed, said bed being thus slightly compressed to retain the moisture andprevent rapid dissipation thereof. A U-shaped reinforcing strap 4extends along the rear and opposite sides of the filler 3 andvisattached thereto, as shown most clearly in Figure 5, and T serves toprevent rapid wear of thefiller." y A standard 5 is attached to theopener by a. heel bolt 6, in a manner well understood in the art, andthis standard has its lower end in contact with the filler 3. and snuglyts within the opener 1. The numeral 7 desig-` nates a' seed spout, ortube, by means of which the seed is delivered into the furrowimmediately in the rear of the bed forming point represented by thefiller 3.'

Two coverers are provided, one for each of the wings 2, and are disposedto operate upon opposite sides of the furrow to eifect discharge of theearth therein to cover the seeds. These coverers are of similar forma-85 tion and each is pivoted to a Wing 2 anda 4spring is associated witheach of the coverers to fyieldably hold-it in working position. Each othe coverers consists of an arm 8 and ablade 9, the same being formedfroml a' uo metalstrap having an end portion twisted' and curved to formthe blade 9. Each of the coverers 8 has a forwardly and down-Y wardlyinclined extension 10 which is laterally offset and pivoted to a v'vino`2, at 11.195 A link 12 is connected to each of thearms 8 adjacent theextension 10 and parallels the latter and engages the inner sideof thewing 2 to which it is connected by the fastener 11.

It' willthus be understood that each of the 100.;

wings 2 iscomprised between an extension 10 of an arm 8 and a link 12,as shown most clearly in Figure 2. The arms 8 are in the planes of therespective' wings 2 'and the blades 9 are oppositely inclined so as tomove 105 -thne earth inwardly to ill th'e lfurrow and i `cover the seed.

A guide tube 13 extends vertically from the rear end of each o f thewings 2 and is longitudinally slotted to receive the arm 8 11o' of a'ooverer. Each of the tubes 13 receives. a spring 14 which is arrangedAto exert a downward .pressure upon the coverer and hold the same to theground with al yield- 4ing pressure depending upon the tension of thespring 14 which is regulated by means of a set screw 15 threaded into aplug 16 closing the upper end of the tube 13. The

set screw is held in the adjusted position by meansV of a binding nut 17A plug 18V loose in the guide tube 13 engages the up er end of thespring Hand the lower end o the set screw 15. .A cross bar 19 connectsthe upper ends of the guide tubes 13 and provides l of the furrow andcompresses the same to form the bed to receive the seed which isdeposited thereon by the spout 7. The wings 2 being elevated abovethebed of the furrow prevent the loose earth from falling upon the bedand seed and disturbing the same. The

.earth is moved inward by\ the blades 9 and 'drops info the furrow andcovers the seed in a manner well understood.

Having thus described the invention, I

claim: Y i

1. A planter comprising an opener and side wings, guidetubes rising fromthe wings and longitudinally slotted, coverers pivoted at their forwardends to the `wings and pass# ing through the slots ofY the guide tubcs,'

springs within. the guide tubes and adapted to exert adownward pressureupon the eov-,

crers and means for adjusting the tension of said springs.

2. A planter con'lprising a runner including an opener and side wings',4guide tubes `rising from the wings and longitudinally slotted, coverers,each 'including an arm and a blade. the arms having a forward extensionwinch 1s` plvoted to one of the wmgs of the runner, a link attached atone end to each of the arms and at its other end to a wing, the wingsVof the runner being disposed between the links and forward extension ofthe arms, springs in the guide tubes and set screws for regulating the'tension of the'springs.

In testimony whereof I affix my signature.
